CMC-RF isolators

We offer Common Mode Chokes / Noise Suppressors / Line Isolators / RFI eliminators for antenna systems operating from 1.8-50 MHz, Our products are broadband units covering a huge portion of the frequency spectrum or single band units covering a small portion of the frequency spectrum with exceptional performances. Our Common Mode Chokes – CMC are carefully designed and measured for maximum resistive choking impedance over the bandwidth desired. If you still do not know why your antenna system needs one, read more about them in Tech. library or Blog by Danny Horvat, N4EXA / E73M.
